Programmed parts marking CYW20706UA2KFFB4G

[BT]

We got these parts from different factory sealed package, but we found some of them contains the additional marking at the bottom which the datasheet didn’t indicated.
Looks like that is kind of programmed marking, but we are not sure. Is there anyone can answer this?

Will that be the original marking printed by Cypress?

Hi BT,

Recommend you to create mycase of "Quality Documentation" type for package top marking information-related query for help.

Thanks,
